CA (Controlled Atmosphere) storage room is a specialized cold storage facility designed to prolong the freshness of fruits and vegetables by regulating the composition of gases within the storage environment.
Case Details
The difference between a Cold storage warehouse and a controlled atmosphere (CA) warehouse is:
CA Storage warehouse have an additional set of air conditioning equipment compared to Cold storage warehouses in terms of configuration
CA systems : The CA SYSTEM including such as nitrogen generator, air compressor, dioxide removal machine, and oxygen and ethylene removal machines and ozone generator.
1-
Airtightness: CA SYSTEM in the requirements for airtightness in the construction process of the care higher than those of adinary fresh-keeping cold storage
2- Preservation principle: The controlled atmosphere warehouse adopts PLC program automation control, which has strong safety and reliability, and high production efficiency.
3- Storage time: Under the same preservation quality and temperature conditions, the preservation time of an air-conditioned warehouse is 3-5 times that of a cold storage, and for some foods, it can even reach tens of times longer
4- Shelf life: The controlled atmosphere warehouse uses inert gas to isolate the air, which can effectively inhibit the respiration and maturation of food cells. This not only prolongs the preservation time, but also extends the shelf life of food after it is released from storage, making it possible to sell food for a longer period of time after it is released from storage
5- Storage method: The controlled atmosphere warehouse adopts the method of whole storage and disposal. That is to say, it is stored once and shipped at once. The taboo thing about a controlled atmosphere storage is to open it frequently, because the composition of the gas inside the storage is very different from that outside. Frequent inflow and outflow of goods greatly reduces the preservation effect after the gas in the controlled atmosphere warehouse runs out
6. Building floors: CA warehouses are generally larger because the price of a set of air CA SYSTEM is around US $15k. It is not cost-effective to make a small cold storage into anCAwarehouse. CA warehouses are usually made in COLD ROOM groups.
6- Cost: Due to equipment costs, the cost of CA storage is high, and the high benefits are also considerable.
